Abstract
An assembling method of a solid oxide fuel cell, having a stack structure in which sheet bodies and separators are stacked in alternating layers, includes a stacking step, a sealing step, and a reduction process step. In the sealing step, a laminate in which a crystallized glass material is interposed between the perimetric portions adjacent to each other is heated, so that the crystallization rate of the crystallized glass is increased to 0 to 50%. Accordingly, the perimetric portions adjacent to each other are integrated and sealed, and a room for glass softening is left. In the reduction process step, the laminate is heated, and a reduction gas is supplied into a fuel channel, whereby the reduction process is performed to the fuel electrode layer, and the crystallization rate is increased to 70 to 100%. Thus, the assembly of the fuel cell is completed.
